WILHELM SPIEKERMANN, F HERZOGENRATH, GERMANY, ASSIGNOR, BY MESNE AS-SIGNMENTS, TO THE AMERICAN BICHEROUX COMPANY, CORPORATION 0F DELA- WAREDEVICE FOR EMPTYING GLASS MELTING POTS Applicationfiled September 10,1929, Serial glass from a pot onto a casting or rolling l il table oronto a receiver or roll of a glass rolling machine on which it isbrought into shape, and it has more particularly reference to the modeof emptying the melting pot for thepouring out of the glass described inthe patents to Max'Bicheroux Nos. 1,673,098 and 1,673,138, according toWhich the pot is emptied en masse7 by positioning the pot near and asideof the table, receiver or other support and turning it as a whole abouta horizontal axis located near the upper pouring edge Yof the pot andslightly above the suport. p The invention has for its object to providea modified form of device of simple and eilicient construction foraccomplishing this mode of emptying the pot, this device having nolonger a pot gripping fork with an offset or cranked shaft, but anordinary pot fork with a straight shaft, this shaft being rigidlysupported by a pair of parallel segments which are mounted for verticalup and down movement about the tilting axis of the pot in the pottransporting apparatus.

The invention further consists iny a suitable driving mechanism forimparting the desired movements to the fork-carrying segments, thismechanism including a worm gear which is self-locking, so that the potcan be securely held at any point of its tilting path Without the use ofspecial locking means.

'An embodiment o f the subject-matter of theinvention is illustrated inthe accompanying drawings, in which Fig. 1 is a side elevation ofthedevice and Fig. 2 a horizontal sectionen the line 2 2 of Fig. 1.

Referring to the drawings, a denotes a glass melting pot, b is the potgripping fork and c is the lower portion of a travelllng crane used forthe transport of the pot. 'I he fork Z; may have the form andconstruction of the forks commonly used forinserting and withdrawing thepots from the melting furnace, but it may also have any other properform.

The frame of the crane c is provided with a number of guide rollers d,between which No. 391,642, and'in Germany `Tuly 3, 1929.

two parallel arc-shaped segments f are mounted forv rotary rup and downmovement in vertical planes. The guide rollers l are arranged withrelation to each other in such a manner that the segments f when movedturn about the tilting axis m of the pot, which is located in or nearthe upper pouring edge of the pot. The fork b has a straight shaftpreferably of square section. It is rigidly mounted by this shaft in thesegments f so that when these segments turn about the axis the fork andpot are likewise turned about the same. The segments f are provided ontheir outer peripheral edge with teeth f which are in engagement withpinions L fastened on a common shaft g. The shaft g further carries aworm Wheel e' with which meshes a worm le which is driven through amotor Z supported on the crane c.

The operation of the described device is as follows: When the grippingfork b has taken a pot, for instance by withdrawing it directly from amelting furnace, t-he crane c carries the pot tothe emptying place, thatis to say to a casting table or the receiver of a rolling machine. Whenin proper position at the machine, the motor Z is started whereby motionis imparted to the described gear parts 7c, z', g, 7L, f and segments f,which cause the pot a to be tilted about the axis fr from the positionindicated by full lines into the position indicated by broken lines,Fig. 1.

VUpon the pot having been emptied by this tilting movement, the4 motor Zis reversed and the pot thereby returned to its horizontal position,whereupon it is carried back by the crane to the melting furnace.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A device for emptying glass melting pots, comprising in combination apot transporting device, a pair of parallel segments mounted in thetransporting device in vertical planes for turning movement about ahorizontal axis, a pot gripping fork with a straight shaft rigidlysupported by the said segments se that the upper pouring edge of thepotis located near the said horizontal axis, and means for impartingmovement yto v Y Lei-@aime the said segments so as to cause them andvthe melting pot to be turned about the said horizontal-axis. y 2.
